COMPANY, A CORPORATION SHAFT-HANGER.

Patented Oct. 9, 1906.

Application filed March 1'7, 1905. Serial No. 250.512.

To all whmn it may concern: I

Be it known that I, LAWRENCE ZAMBONI, a citizen of the United States, residing in Philadelphia, county 01 Philadelphia, and State of Pennsylvania, have made a new and useful Invention in Shaft-I-Iangers, of which the following is a specification.

My invention is directed particularly to improvements in tubular shaft-hangers constructed of pressed metalsuch, for instance, as are usually made by pressing in a die the different half members of the hanger and securing the same together by rivets, the jourrial-bearings being adjustably sustained by screws extending through the lateral and vertical members; and it has for its objects, first, to devise a hanger of this type which shall be constructed of the fewest possible number of parts and shall possess maximum strength and minimum lightness; second, to devise a hanger of this type in which all of the members shall be so constructed and interconnected as to afford, so far as possible, a

minimum surface for the collection of dust,

grit, or dirt. I

My invention will be fully understood by referring to the accompanying drawings, in which- Figure 1 is an elevational view of a com plete hanger, illustrating the manner of securing one of the journal-bearings of a line of shafting thereto, one portion of the hanger on one side being broken away for the purpose of better illustrating the interior structure and interconnected adjustable parts. Fig. 2 is a side elevational view of Fig. 1 as seen looking thereat from right to left. Fig.

. 3 is a vertical sectional view taken through Fig. 1 on the broken line X X and as seen looking thereat from left to right in the direction of the arrows. Fig. 4 is a plan view as seen looking at Fig. 1 from the bottom toward the top of the drawing. Fig. 5 is a transverse sectional view taken through Fig. 1 on the line Y Y and as seen looking thereat in the direction of the arrows from the top toward the bottom of the drawing. Figs. 6 and 7 are sectional views of modified forms of the vertical members, illustrating different ways of securing two parts of such members together.

In the manufacture of tubular hangers of pressed metal as heretofore constructed it has been customary to form the same of a number of pressed parts held together by rivets or in any other preferred way and to secure the journal-bearings of the shafting between the vertical and horizontal members by adjustable devices. With all such hangers, however, so far as I am aware, there has been no attempt made to so construct the entire hanger that it will be free from the collection of dust, grit, or dirt which usually prevails in large manufacturing establishments, so that the same accumulates in relatively large uantities and necessarily at points near he journal-bearings, thereby materially damaging the journals by reason of the cutting action thereof as time advances; nor is it possible with such hangers to. effectually remove the dust or grit.

My improvement not only effects the very desirable result referred to, but by reason of the structural arrangement of the several parts I am enabled to utilize a minimum number of parts and to so assemble the same as to give to the vertical members a tubular structure, also of great strength, and to the horizontal members a web structure, also of great strength, both the tubular and web structures being rigidly secured together by rivets and in such manner that there result no pockets or depressed surfaces for the accumulation of dust or dirt. this effect by constructing the vertical mem-- bers, the top or sustaining member, and one of the lower horizontal journal-sustaining members of two pieces of pressed steel, the bottom horizontal journal-sustaining member being detachable and made also of two pieces of pressed steel. I then unite the two parts of the members together by rivets and provide a cover for the upper portion of the top or sustaining member, all being so arranged, as illustrated in the drawings, that when the parts are finally secured together and to the ceiling or the horizontal trusses of a factory-building, where such hangers are usually sustained, the best results are obtained.

For a full and clear understanding of my invention, such as will enable others skilled in the art to construct and use the same, reference is had now to the drawings in detail,

I accomplish in all of which like numerals represent like or equivalent parts wherever used.

1 1 represent vertical members of the two halves of a hanger, each so pressed in a die as to give to it the conformation shown-that is to say, two vertically-disposed members, a horizontal top or sustaining member 2 of substantially web form, and a central member 3 of I-beam form, the latter of which is designed to constitute the upper support for the adjustable means which carry the journal-bearing. The lower ournal-sustain iIIg member 4 is in like manner composed of two parts of pressed steel having webs or flanges and secured together by rivets, as shown, its outer ends being adapted to straddle the squared lower ends of the vertical members. The central member 3 and lower member 41 have when the parts are put together in the manner shown vertically-arranged cylindrical openin s 5 5, and the top or sustaining member 2 and lid or cover 6 therefor are provided each with two depressions 7 7, adapted to fit within a pair of sleeves 8 8, one of which only is shown in Fig. 1. This lid or cover gives greater strength to the structure and closes the cavity in the horizontal top or sustaining member 2. Each half of the vertical members is provided near its lower end with semicylindrical openings 9 9, screwthreaded interiorly.

1.0 is a two-part ournal-bearing, and 11 11 11 are set-screws for adjusting said journalbearing vertically and laterally in the hanger.

12 12 are shouldered screw threaded sleeves seated the upper one in the central 'member 3 and the lower one in the lower member 4, and 13 13 are set-nuts for finally securing the set-screws 11 11 1]. after -the proper adjustment has been effected.

14 14 are bolts for detachably securing the lower journal-sustaining member 4 to the squared lower ends of the vertical members 1 1. I

It will. be noted that when all of the parts of the hanger are secured together by rivets, as shown, and the lid or cover 6 similarly riveted to the outwardly-extending flanges of the horizontal top or sustaining member 2 the loWer member 4. may be secured directly to the lower ends of the vertical members 1 1 by the bolts 14 14 and that after the complete hanger has been secured to the ceiling by bolts extending through the top or sustaining member 2 and lid or cover 6 the journal bearing 10 may be secured in place by the set-screws 11 11 1.1., screw-threaded sleeves 12 12, and set-nuts 13 13 13.

It is apparent that by reason of the peculiar structural arrangement of the parts, as described, there are no pockets, cavities, or openings which will accumulate dust, grit, or dirt, the screw-threaded sleeves 12 12 and set-nuts 13 13 effectually closing the vertical openings extending through the members 3 and 4, so that it becomes a simple and easy matter to effectually removeall dust which may accumulate upon such a hanger, and this with an ordinary dust-brush and without having to use a step-ladder.

By reason of the small number of parts and of the peculiar tubular formation of the vertical members and web and I-beam conformations of the horizontal journal-sustaining members I have devised a structural hanger of great strength and minimum lightness and also a minimum number of parts, and while I prefer to secure all of the individ ual parts of the members by rivets, in the manner shown, extending through flanges of the vertical members and through the body of the horizontal members I do not limit the structural arrangement to this particular feature, as obviously the same may be secured in various ways. To illustrate, in Fig. 7 I have shown how th s may be effected by an overlapping joint.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A pressed-metal shaft-hanger embracing a horizontal top sustaining member; two vertical members and a horizontal central sustaining member composed of two pieces of metal and all of said parts held together by rivets, the upper horizontal and two vertical members when held together being hollow and closed at all points so as to preclude the admission of dust, the central horizontal member being of I-beam form; in combination with a lower horizontal sustaining member composed of two parts held together by rivets and of I-beam form and a journalbearing; together with horizontal and vertically-disposed set-screws arranged in pairs, one pair extending laterally through openings in the vertical members and the other through screw-threaded sleeves in openings between the horizontal sustaining members, substantially as described.

2. A pressed-metal shaft-hanger embracing the following elements; two verticallydisposed members; a horizontal top sustaining member and a horizontal central member, all composed of two pieces of metal and having the conformation shown, and held together by rivets, the top sustaining member being provided with a lid or cover secured to its upper surface by rivets; in combination with a lower horizontal sustaining member composed of two parts held together by rivets and .of 'I-beam form, said lower member being supported at the lower end of the vertical members by bolts and the central and lower members provided with vertically-disposed cylindrical openings; vertically-dis posed screw-threaded sleeves located in said openings and vertically and horizontally disposed set-screws extending in pairs respecname to this specification in the presence of tively through the aforesaid sleeves and the two subscribing Witnesses.

vertical sustainin members for effecting adjustment of the Tournal-bearing, all of said J LAWRENCE ZAMBONI' 5 parts acting substantially as and for the pur- Witnesses:
